I just got it back from my stripper (ooh, this is porn;)). It looks good, I can't see any stress cracks or problem areas :thumbsup: . The filleting has some tiny "air bubble" holes that I'd like to fill, anyone have any ideas how? It's gotta be a metal based filler as I'm going to powdercoat it Gloss Metallic Black. Sorry for the lousy pics, I'll do better later.

And a question...are filleted frames tigged first and then filled or is the filleting holding the whole thing together? I guess I'm wondering if filleting is kind of like soldering?

looks neat. I like the canted rear dropouts like Ritchey did. Those little air pockets are normal. I think theyre from impurities in the brass if I recall. You can fill them in with a touch of bondo if youre gonna use wet paint or maybe some solder if youre gonna PC.


and yes, the brass alone holds it together. no TIG underneath.

Bondo is sorta overkill for those tiny spots. This stuff is much, much easier to work with...

that's what I thought....

Actually those fillets aren't bad at all. I wouldn't want to clear coat it, but under paint, they'll look fine and the size and radius are good.
I'm certainly not an expert but I thought they looked pretty good too. I like the proportions of the fillets relative to the tubing size.:thumbsup:

Too bad it looks like the blast media was too big/coarse.
What do you see/why do you think so and how can you tell?

He's done 4 other frames for me using the same procedure and they came out great.

Stan, If your powdercoater is nice have him build up the areas that have the air bubbles or pitting with a thick pass of powder coating. After those areas are filled they are then sanded down flush. Then the final coat is applies and viola!! SMOOOOOTTHHHHH.
